Oddly, I've noticed a different bug with that list: a question that has been closed and reopened will be listed under the close votes section with some (usually high) number of close votes, but the question page shows no current close votes. This questionThis question is a good example (currently top of the most close votes listtop of the most close votes list in the 7-day view).
I can only see the tools on Super User, but I've never noticed the behavior you describe.
